No particular question here. I've only started pulling sumo in the past week or two, I'm really loving it so far. The first video I couldn't get to the gym so I was messing around in my friend's garage where I have access to max of 135lbs. Figured I'd so some speed work and drill the form into my head. Second video I was pretty fatigued already having gone through a squat PR, some bench sets, weighted pull ups, and a few heavy conventional and warm up sumo sets. I figured my form would be breaking down at this point so it's good chance to get a legit form check. I can spot a few things wrong but I want to see what you guys notice and suggest first. Thanks.

Those 2 don't really work together. If you're doing speed work you're focusing more on being explosive.

For your form:
Try to setup with the bar nearly touching your shins as you're standing up, you won't be pushing your knees forward as much as sideways. You want to be pushing them out to the sides (like a frog stretch).

Be sure to lean back onto your hips as you start the lift, in some of the reps they come up and it looks more like a conventional DL.

Go shoeless or get some shoes w/stiff sole, I noticed your toes coming up during some of the reps.

It looks like you're bending your elbows at the top of the lift, can't really tell because the plates are in the way. Just make sure you're not trying to curl it.
